"Our vinvention relates to easementv window adjusters, and hasparticular reference to that type of adjuster having an armor linkpivotally supported on the stool or trame of the 'window and vhaving itsouter end sl'idably upported in-a guide carried on the window.

One of'the objects of lthe invention is tov provide an adjuster which isof very simple and economical construction, Which is operable with onehan-d, and Vwhich automatically and positively will tasten a easementwindow in vopen position'and vwhich readily may be adapted to all typeso1 easement windows. y f

Another object of the invention is to provide an adjuster so constructedthat allv ot its exposed surfaces may be painted for the sake ofappearance and to resist rust.

Another object of the invention is to provide an improved constructionof guide channel for mounting on the Wintrow,

Our invention has unique application to metallic windows and metallicwindow frames, and 'for the purpose of showing a typical*installationotthe'invention, We have shown the same mounted on a window and windowtrame of this construction, but it is vto be understood that theinvention is not to be limited to use 4on metallic windows.

ln the accompanying .drawing illustrating our invention:

Figure 1 is a fragmentary inside elevational view of a easement windowto which slide, taken substantially on the plane 01"" the line 3,-3 otFig. 1;

Figure a is a longitudinal sectional view through the Ouide member,taken .substantially on the plane of the line l--l101e Figure 3';

Figure is av detailedvsectional view taken substantially on the plane ofthe line ofllig. 3,\and- Y FigureS-i's a transverse sectional viewthrough the pivot bracket ofthe link,I taken on' the plane ofthe line 66 of Figure 1J rlhel top, bottom andl side rails ot' .the metallicwindow sash'Q consists yof bars' 11v having inner jan'd outer parallelflanges `12 and 13 'somewhat like Zibars. The Windev:7 trame 17 isconstructed or" a duplicate ar# rangement of bars 18 having parallelflanges 19' and 2O like the bars 1'1.v i A,

Secured to this window andv Window trame isthe present adjuster, whichcomprises the inner pivot bracket 22, which .is securedto the windowframe l?, the guide channel 23 which isfsecured' tothe window, and thelink which' connects these two'. l, Y lThe pivot' bracket 22 comprisesaright angle attaching portion/,25 which lis secured to the lower rail 18of 'the' window frame. Forinaking this attachment, th'e innerliang'e19er this rail' is notched out indicated atl 26 in Figure 1', and theangle portion 25ct the bracket is setint'o'this notched out area. Thehorizontal leg ofthe anglel portion is riveted or screwed ltothe webv otthe rail 18, as indicated at 27. This leaves alvtiush survtaceonboththeinner and f'ut'ersides roit-he i la-nge,19,pthus permittingilusli 'seatinguof the flange 12 ofthe window', along th'e'in'iierhang-e ot thetrame rai'l'jand presenting a neat appearingv traine railfrom the inner side ot''thezwindow` l Y From the angle por-tion 25, thebracket is bent back and then folded overto ktorni a tlv-'shaped portion28, between the arms of which the link 2l is pivotedl YA' screwv 29passes through they Usha-ped portion and Vthrough the link,threading'into the bottom of the lli-shaped portion. lt will be under#stood that this pivoty bracket can be secured to the stool of the windowtrame, i1"`=desired. The guide member 23consists of' asta-mping foldedto provide a. guilde channel of box-,like section (Figure y3) andcomprises an outer vertical flange 3,1, ahorizonta'l top flange 32an`inner verticalliange 33, and a bottom flange 8d. Theouter edge of thebottom flange Ell terminates short of the outer vertical flange 3l toleave auslot 35 enn tending the length of the guide. Adjacent its ends,`the guide membery has depending portions 37 Which are secured by rivets38 to attachingA angles 39.1 vvThe inner flange 12 of thevvvindowis-notched out at pointsadjacent the ends of the guide member to receivethe attaching angles, which are riveted to the webs of the window railsll, as indicated at 4l. This attachment leaves a flush inner face alongthe inner-'surface of the rail 11 for contacting with the flange 19 ofthe frame rail. At predetermined points along the bottom flange 34 ofthe guide there are provided fastening apertures 42 which, as shown inFigure 5, are slightly elongated transversely of the guide. The sides ofthese apertures form fastening shoulders for cooperation with afastening projection on the slider 44, which we shall now describe.

.The releasing of the adjuster, the swinging'of the window, and therefastening of the adjuster, is all performed through the direct manualoperation of a li'ftable fastening slide 44 which is secured to theouter end of the link 24 and slides in the guide 23. As shown in Figure3, this manually liftable fastening slide consists of a stamping havingya U-shaped portion 45 lying directly beneath the guide 23. The link 24 fis secured in this dropped portion of the slider by a rivet 46. Theinner end of the slide member passes up through the slot 35 and isprovided with a backwardly bent hook flange 47 which rests upon thefastening flange 34 of the guide. A fastening projection 48 is securedto this flange of the slider `for reception in the fastening apertures42 of the guide. This fastening projection has a reduced upperV endwhich passes up through the flange 47 and isriveted over on the upperside of a leaf spring 51.. The upper ends of this leaf spring bearagainst the top wall 82 of the guide and press the projection 48downwardly on the fastening flange ofthe guide for snapping into thefastening projections 42.

As shown best in Figure 5, the outer wall of the slider is given a dullpunching to project a rounded'nipple or bearing projection 53 from itsouter sideV for bearing against the adjacent wall of the guide. Thisrounded bearing contact maintains contact with the side wall of theguide in the slight pivotal turning of the slider member incidental tothe angular movement of the link.

The outer end of the slider is extended upwardly and looped over toprovide an operating handle 55 in the form of a Alinger pull which thefinger can be hooked under for raising the fastening slide and shiftingit along the guide for opening or closing the window. Upon releasingthis hookdike handle 55 the fastening projection 48 is allowed to snapinto the end nearest adjacent the fastening aperture 42 under the actionlof the leaf spring 5l.

The pivot bracket 22 of the guide channel 23 and the link 24 areuniversal for adapting the adjuster to al lefthand window is the turningof the fastening slide 44 on the end of the link so that it will face inthe opposite direction. The fastening apertures 42 may be given anydesired arrangement and spacing, it being generally Adesirable thatthere be a plurality of aperturesadjacent the ends of the guide forrelatively line adjustment of the window in its substantially closed andwide open positions. The similar spacing of these apertures adjacent theends of the guide also adapts the guide to right and left-handinstallations.
